Description

Technical Field

[0001] The utility model relates to display technology, in particular to a frame sticker structure of a narrow frame panel. Background Art

[0002] There are two ways to bond the display panel to the protective cover or touch screen: one is the frame bonding method based on the opening glue, and the other is the full bonding method based on the OCA glue. With the development of narrow frame technology of display panels, the frame width of LCD panels is only about 1.2mm, and even the frame width of some OLED panels is less than 1.0mm.

[0003] When the border width is extremely small, if the display panel and the protective cover or touch screen are fixed by frame pasting, the area on the display panel where the adhesive can be pasted is insufficient and the stability of the frame pasting is insufficient. Therefore, the display panel and the protective cover or touch screen can only be fixed by full pasting.

[0004] However, some application scenarios require that the display panel and the protective cover or touch screen be fixed by means of a frame sticker. For example, in automotive products, the vibration of the vehicle will be transmitted to the display panel through the protective cover or touch screen. If the display panel and the protective cover or touch screen are fixed by means of a frame sticker, the air layer formed by the frame sticker will have a buffering effect on the vibration, which can reduce the transmission of vibration and avoid defects in the display panel due to vibration.

[0027] The frame-sticking structure of the present invention adopts a double protective cover plate design. The display panel 30 and the second cover plate 20 are fixed in a full-fitting manner to meet the bonding stability requirements of the display panel 30 and the protective cover plate under narrow frame conditions. The second cover plate 20 and the first cover plate 10 are fixed in a frame-sticking manner to meet the buffering and vibration reduction requirements of the display panel 30 and the protective cover plate in vehicle-mounted application scenarios. When the whole machine is assembled, the first cover plate 10 is fixed to the whole machine casing, and the vibration of the vehicle is first transmitted to the first cover plate 10 through the whole machine casing, and then successively transmitted to the display panel 30 through the first cover plate 10 and the second cover plate 20. Since the first cover plate 10 and the second cover plate 20 are fixed in a frame-sticking manner, the air layer a formed by the frame-sticking has a buffering effect on vibration, which can reduce the transmission of vibration and avoid the display panel 30 from being defective due to vibration. At the same time, since the second cover plate 20 and the display panel 30 are fixed in a full-fitting manner, the bonding stability of the display panel 30 is guaranteed.

[0034] like Figure 2 As shown, the first cover plate 10 includes a light-transmitting area 11 and a peripheral area 12, and the peripheral area 12 surrounds the light-transmitting area 11; the light-transmitting area 11 of the first cover plate 10 corresponds to the display area 31 of the display panel 30, and the peripheral area 12 of the second cover plate 20 extends outside the second cover plate 20. The peripheral area 12 of the second cover plate 20 exceeds the area of ​​the second cover plate 20 for fixing to the housing of the whole machine when the whole machine is assembled.

[0035] The light-transmitting area 11 of the first cover plate 10 may be slightly larger than the display area 31 of the display panel 30 to meet the fitting tolerance requirement, and a distance of 0.5-1.0 mm is reserved between the edge of the light-transmitting area 11 and the edge of the display area 31 .

[0036] like Figure 1 As shown, the frame-sticking structure further includes a light-shielding ink 60 , and the light-shielding ink 60 is disposed on the peripheral area 12 of the first cover plate 10 facing the second cover plate 20 .
